Private IPv6 address range

Here is a unique private IPv6 address range generated just for you (refresh page to get another one):

Prefix/L:

fd

Global ID:

6da28b43f7

Subnet ID:

052c

Combined/CID:

fd6d:a28b:43f7:052c::/64

IPv6 addresses:

fd6d:a28b:43f7:052c:xxxx:xxxx:xxxx:xxxx

If you have multiple locations/sites/networks, you should assign each one a different "Subnet ID",
but use the same "Global" ID for all of them.

The IPv6 address space is so huge (2128) that everyone should
be able to get a public IP address for every device they will ever own. So theoretically
it shouldn't be necessary to have private IPv6 addresses like the 192.168.x.x and 10.x.x.x
addresses in IPv4.

However until you can actually get an IPv6 address range from your ISP, you may want to
use "private" addresses for internal networks and testing etc.
In IPv6 there is a special "Unique Unicast" IP range of fc00::/7 which should be used for this as per
RFC4193.
The official definition looks like this:

In practice such address will always start with "fd" because the 8th (L) bit must be one.
The "Global ID" and "Subnet ID" must be random to ensure uniqueness (which is what this page does).
You are free to assign addresses from the rest (Interface ID).

Please note:
A former standard proposed the use of so-called "site-local" addresses
in the fec0::/10 range.
This has been deprecated (see RFC3879) and should no longer be used.
